Wayland Supports Multiple Mouse Cursors

A recent post on the developer‑focused site blinry.org, titled “multi‑seat Wayland,” outlines how the Wayland display server protocol can be configured to support multiple independent user sessions on a single machine. The article explains the underlying concepts of “seats” in Wayland, details the necessary configuration changes, and demonstrates a proof‑of‑concept implementation that allows two users to log in simultaneously with separate input and output streams.

The post delves into the technical steps required to enable multi‑seat functionality, including modifications to the compositor configuration, the use of the `wl_seat` interface, and handling of shared resources such as the graphics buffer and input devices. It also discusses the security implications of running multiple seats, the performance overhead, and the compatibility considerations with existing Wayland clients. By providing code snippets and a step‑by‑step guide, the author aims to lower the barrier for developers interested in deploying multi‑user environments on Linux systems that rely on Wayland.

The article has attracted attention on Hacker News, where it received 40 upvotes and 17 comments, indicating a moderate level of interest among the community. Readers in the discussion have highlighted practical use cases such as shared workstations and educational labs, while also noting the need for further testing on various compositors. Overall, the post contributes to the ongoing conversation about expanding Wayland’s capabilities beyond single‑user scenarios.
